The A's will call up right-handed relievers Ross Wolfand Justin Jameswhen rosters expand today, according to several sources, and the latter is a particularly unexpected but interesting addition.

James, who turns 29 this month, was discovered in the independent Northern League in June, and he pitched well at Double-A Midland - and then even better at Triple-A Sacramento, with a 1.37 ERA and 28 strikeouts and nine walks, in 19 2/3 innings.

So in just more than two months, James, who spent time in the Blue Jays' and Reds' organizations, will have gone from the Kansas City T-Bones to the A's. He's not on the 40-man roster, but Oakland has an open spot after optioning Matt Watsonto Sacramento.

Wolf was little used when up before, at one point going 21 days without an appearance, the second-longest such stretch in the majors this year.

Everidge back in fold: The A's re-signed first baseman Tommy Everidgeand assigned him to Sacramento.

Everidge, who is from Sonoma, made a splash when he came up last year, hitting .295 in his first 12 games, prompting fans to bring signs reading "Tommy Time" to the Coliseum. He since had gone to the Mariners' organization and then to the Astros.

The River Cats needed reinforcements because Chris Carteris on the disabled list with a sprained thumb,Watson jammed a pinky sliding into second, and Dallas McPhersonhas hamstring tightness. Outfielder Corey Brownwas promoted from Double-A Midland to help, too.

AFL rosters announced: Oakland will send some high-profile players to the Arizona Fall League to play for Don Mattingly, including outfielder Michael Taylor, a former Stanford player who was thought to be a possible contributor in Oakland this year.
